Dephasing and delay time fluctuations in the chaotic scattering of a quantum particle weakly coupled to a complicated background
Valentin V. Sokolov
Effect of a complicated many-body environment is analyzed on the chaotic motion of a quantum particle in a mesoscopic ballistic structure. The dephasing and absorption phenomena ar…
Chaotic scattering of a quantum particle weakly coupled to a very complicated background
Valentin V. Sokolov
Effect of a complicated many-body environment is analyzed on the chaotic motion of a quantum particle in a mesoscopic ballistic structure. The dephasing and absorption phenomena ar…
Is the concept of the non-Hermitian effective Hamiltonian relevant in the case of potential scattering?
D. V. Savin, V. V. Sokolov, H. -J. Sommers
We examine the notion and properties of the non-Hermitian effective Hamiltonian of an unstable system using as an example potential resonance scattering with a fixed angular moment…
Distribution of proper delay times in quantum chaotic scattering: A crossover from ideal to weak coupling
Hans-Juergen Sommers, Dmitry V. Savin, Valentin V. Sokolov
The probability distribution of the proper delay times during scattering on a chaotic system is derived in the framework of the random matrix approach and the supersymmetry method.…
